SWAGING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 542,020, dated July 2,1895. Application led October 13, 1394. Serial No. 525,827. (No model.)

To alZZ whom it may concern:

Be it known that I, ANTolNE. J. LANGELIER, a citizen of the United States, and a resident of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Swaging-Machines, of which the following is a specification.

My invention relates to the improved means employed to effect a closing or opening movement of the swaging-dies while the machine is in operation; and it consists in the employment of an angnlarly-adjustable block and a sliding shoe between the swaging-die and the engaging die-block, as hereinafter fully set forth.

In the accompanying drawings, Figure l represents a front elevation of `the machine with the front plates removed. Fig. 2 represents a side elevation and a partial. section. Fig. 3 represents an axial section of the dieholdingspindle,showinga modification. Fig. 4 represents an axial section of the die-holding spindle, showing another modification.

In the drawings, A represents the stationary head, in which is journaled the die-holding spindle B, to which rotary motion is imparted by means of the pulley C. The head A is provided with the beatingrollers a a, which are adapted for engagement with the sliding die-blocks D D to cause the proper reciprocation of the swaging-dies E E, the

said engaging die-blocks and swaging-des being loosely held in the diametrical groove j, made in the enlarged forward end of the holding-spindle B, and between the swagingdies E and the engaging die-blocks D in the groove j are placed the angularly-adjustable blocks F F, having rounded ends, and provided at their inner rounded ends with a sliding shoe G, by the movement of which the distance between the working faces of the swaging-dies and the engaging die-blocks may be either increased or diminished to the limited extent required. The enlarged forward end port-ion of the die-holding spindle B is provided with the perforations h h, adapted to receive theparallel rods c c, which at their forward ends bear against the rear edge of the sliding shoes G, and are secured at their rearward ends to the sliding sleeve H, to which operative connection is made by means of the ring I fitting loosely in the circumferential groove d of the sleeve, and connection is made from the ring I to an operative treadle by means of the toggle-jointed arms e e', the arm e being jointed to the ring I by means of the screws lf and the arm ejointed to the bearing-standard g of the head A by means of the screw f', and to the middlejointfz-is attached the downwardly-extending link h, which is connected with the treadle, the said link and treadle being caused to rise by means of a spiral or other suitable spring i, and upon the downward movement of the treadle by the operator of the machine the sleeve H will be thrown forward, thus forcing forward the sliding shoes G and changing the angular position of the adjusting-blocks F F, thus increasing the distance between the swagingdies E and the engaging die-blocks D,so that the dies will be brought closer together upon the engaging impulse of the beating-rollers a. The several parts are held in position. in the groovej of the die-holding spindle by means lof the face-plate J which is secured to. the

front face of the spindle by meansot' screws, and the reverse movement is imparted to the sliding slices G by means of the springs Z, secured to the front of the face-plate J, which springs act upon the projecting forward ends of the said shoes.

Amodicatiou of my invention is shown in Fig. 3, in which the sliding shoes G are shown at the outer instead of the inner end of the angularly-adjustable blocks F F, and in this case the desired movementof the shoes is produced by means of the bellcrank levers m, which are connected by means of thelinks n with the rods c, which rods are connected with the sliding sleeve H, and upon the forward movement of the sleeve H the swagingdies will be brought closer together, as before.

Another modification is shown in Fig. 4, in which the angularly-adjustable blocks F F are provided with a rearwardly-extendin g arm 7o, to which the links n are connected, and in this case the springs Z for operating the shoes in the reverse direction are dispensed with, the said angularly-adjustable blocks being ICO positively connected with the sleeve H, so as 1. In a swaging machine, the combination of the beaters,vthe swaging dies, andthe engaging die-blocks, with the angularly adjustable blocks, and means for changing the direction of the axesiof the adjustable blocks while the machine is in operation, substantially as described..

2. In a swaging machine, the combination of the stationary head, and the beatingurolb. io ers, with the rotary spindle provided with `the chine is in operation, substantially as de- T5 scribed. l ANTOINE J. LANGELIER.
